Finally, the invention also provides a use method of the filter, which comprises the following steps:
diesel engine tail gas gets into from straining a section of thick bamboo shell 3 and strains an interior, filters the solid particle thing in the tail gas through inside filter media 2, and the tail gas after filtering is through straining a section of thick bamboo inner shell 4, filters absorption tail gas once more through active carbon 5, and solid fixed ring 1 discharges in the atmosphere from straining a section of thick bamboo at last, accomplishes the filtration to particulate matter and harmful gas in the tail gas, realizes the protection to the environment.
The filter can well reduce particulate matters and harmful substances in the tail gas of the diesel engine, solves the problem of high cost of a post-treatment carrier scheme to a certain extent, and meets the requirements of reducing emission and protecting the environment.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents or improvements made within the spirit and principle of the present invention should be included in the scope of the present invention.
